Most parts of the ruins, which are on ground in Phaselis, are remains from the Roman period. A port, castle among these ruins have been found the remains of a port, castle walls, a temple dedicated to Zeus, King Antonius Caravella road, and also twenty lined theater ruins. The peninsula's throat part composing street is marvelous. It begins from south port and reaches to city gates.
